President Donald Trump’s eldest son Donald Trump Jr. deserves to be deported for hunting and killing an elephant and other wildlife, animal rights activists demand.

People for the Ethical Treatment of Animals (PETA) announced Friday it plans to put up a billboard in towns bordering Mexico features an infamous image of Trump Jr. holding a knife and the tail of an elephant he apparently shot abroad.

PETA’s announcement comes as the president sends troops to the Mexico border to prevent asylum seekers from entering the U.S.

“President Trump is talking about bad hombres and undesirables and how people approaching the border want to come into this country to rape and steal,” PETA President Ingrid Newkirk told Newsweek. “So I thought, well my goodness, he could look closer to home. His own sons are people who go to other countries and then blow away wildlife.”

Trump Jr. “has a history of self-aggrandizement at the expense of wildlife in the U.S. and abroad,” PETA stated.

He and his younger brother Eric Trump have come under fire for photos from hunting trips in which they pose with a dead elephant, waterbuck, civet cat and kudu.

Facing criticism in 2012, Trump Jr. tweeted, “I'm not going to run and hide because the peta crazies don't like me.”

The animal rights group has sent “huntsman condoms” to the Trump brothers and other hunters to purvey the message that they should stop reproducing.

PETA has welcomed asylum seekers to the U.S.

“I thought this is really unfair that the immigrants or would-be immigrants are spoken of as if they are all undesirables when every country has highly desirable and worthy people,” Newkirk said on Friday.

“And there are those who are not, who are just plain outright cruel and rotten,” she said, referring to Trump’s sons.

The Trump administration last month quietly made it legal for Americans to bring elephant tusks and other body parts to the U.S. as trophies.

"The ice doesn’t care what this administration thinks. It’s just going to keep melting," David Titley, the director of the Center for Solutions to Weather and Climate Risk at Penn State, told Newsweek.
